Doctor Answers (1) on Lice problem

Over the counter medications available in the stores you can try that...Lice usually don't live past one day without feeding from a scalp, and eggs do not survive if they aren't incubated at the temperature near the scalp. Therefore, the chance of lice surviving on household items is small.
As a precaution you may clean items that the affected person has used in the last two days. Cleaning recommendations include the following:
Wash items in hot water. Wash bedding, stuffed animals and clothing in hot, soapy water — at least 130 F (54.4 C) — and dry at high heat.
Clean hair care items. Clean combs, brushes and hair accessories in hot, soapy water.
Seal items in plastic bags. Seal items that cannot be washed in plastic bags for two weeks.
Vacuum. Give the floor and upholstered furniture a good vacuuming.
